Abstract

Purpose: To measure the in vitro fluoride release from three polyacid-modified resin-based composites (Dyract AP, Compoglass F, F2000) and one resin-modified glass-ionomer cement (Vitremer VLC) for 28 days in two different buffer solutions. Material and Methods: 30 cylindrical specimens of each material were prepared. Subsequently, 15 samples of each material were stored in neutral (pH 6.8) and acidic (pH 4.0) buffer solution (5 mL), respectively. After 4, 8, 12 hrs and 1, 2, 4, 8, 14 days, respectively, the samples were transferred into new solutions. The fluoride content was determined witha fluoride sensitive electrode. Data were analyzed with ANOVA, followed byclosed-test-procedure based on Kruskal-Wallis. Results: Compared to the neutral solution, all materials showed a significantly higher release of fluoride in acidic environment within the 28-day period (P < 0.001, ANOVA). In acidic buffer solution Vitremer VLC and Compoglass F showed a significantlyhigher fluoride release than F2000 and Dyract AP (P < 0.001, closed-test-procedure). In neutral solution Dyract AP showed the significantly lowest release (P < 0.001, closed-test-procedure). Fluoride release from the materials tested is higher in an acidic environment than in a neutral environment.
